How do I create a modal dialog box from within a regular DLL?

|  Overview |  How Do I |  FAQ |  Details |  Sample

When creating a modal dialog box from within a regular DLL statically linked to the MFC, you must pass a valid parent window object to the CDialog constructor. For more information on creating a modal dialog box in a regular DLL that statically links to MFC, see the Knowledge Base article, “How to Create a Modal Dialog from Within a USRDLL” (Q121947). For sample code that creates a modal dialog box, see the sample .

Note that the term USRDLL is no longer used in the Visual C++ documentation. A regular DLL that is statically linked to MFC has the same characteristics as the former USRDLL. The advice in the Knowledge Base article also applies to regular DLLs that are dynamically linked to MFC.

Feature Only in Professional and Enterprise Editions   Static linking to MFC is supported only in Visual C++ Professional and Enterprise Editions. For more information, see .
